COMPACT MINIATURE FIRE-EXTINGUISHING AND/OR FIRE-PROTECTION DEVICE

摘要

A fire-extinguishing or fire-protection device formed from a pressure vessel filled with a pressurized extinguishing medium. The device has an exit opening closed by a closure element which can be perforated by a perforation element. The pressurized extinguishing medium is held back in the pressure vessel from a passively thermally controlled trigger valve attached directly to the exit opening. The valve has a perforation element and a thermal triggering element. The perforation element is prestressed in a triggering position and is retained by the thermal triggering element in a standby position. When the triggering element is triggered as a result of a predetermined temperature being reached, the perforation element is released moving the triggering element to the triggering position in which it perforates the closure element. A thermal trigger valve suitable for use in the fire-extinguishing or fire-protection device is disclosed.
